fn (x) = f(x). n2x if 0 ≤ x if 1 n ≤ x 0 if 2 n ≤ x ≤1
... width is 2/n. so you get 1 for each integral. This of course converges to 1! c. What function, f, does the sequence of functions converge to pointwise? Any positive number is less than some value of 2/n (by A.P.) So for any point in (0,1) the sequence fn(x) converges to zero. The sequence may get pr ...

9 | Separation Axioms
... Separation axioms are a family of topological invariants that give us new ways of distinguishing between various spaces. The idea is to look how open sets in a space can be used to create “buffer zones” separating pairs of points and closed sets. Separations axioms are denoted by T1 , T2 , etc., wher ...

... last year’s mid-term test. Your task is not just to say what was meant, but to try to make some helpful comment which will clear up the misunderstanding that led to each statement. (a) f is not surjective, since not every input has an output; (b) f is not surjective, since f (1) has no input; (c) f ...

δ-CONTINUOUS FUNCTIONS AND TOPOLOGIES ON FUNCTION
... Theorem 3.17. Let Z ⊂ SD(X, Y ). A topology τ on Z is strongly δconjoining iff for any net {fµ }µ∈M which converges ([5]) to f in (Z, τ ) implies that it strongly δ-continuously converges to f in Z. The proof is similar to that of Theorem 3.15. 4. The Concept of Splitting Topology in Function Space G ...
